单选题Today's students have grown up hearing more about Bill Gates than F. D. R., and they live in a world where amazing innovations (革淅) are common. The current 18-year-olds, after all, were 8 when Google was founded by two students at Stanford; Mark Zuckerberg founded Facebook in 2004 while he was at Harvard and they were entering high school. Having grown up digital (数字的), they are impatient to get on with life. The easiest way to find kids like these is to check in on entrepreneurship (企业家才能) education, in which colleges and universities try to prepare their students to recognize opportunities and seize them. A report published last year by the Kauffman Foundation, which finances programs to promote innovation on campuses, noted that more than 50,000 entrepreneurship programs are offered on two-and four-year campuses--up from just 250 courses in 1985. Lesa Mitchell, a Kauffman vice president, says that the foundation is extending the reach of its academic influence, which used to be found only in business schools. Now, the concept of entrepreneurship is blooming in engineering programs and medical school, and even in the liberal arts. "Our interest is the programs," she says. "We need to spread out from the business school." Either as class projects or on their own, students in a variety of majors are coming up with ideas, writing business plans and seeing them through to prototype and, often, market. In their spare time, students in agricultural economics at Purdue invent new uses for bean; industrial design majors at Syracuse, in special laboratory, create wearable technologies. (78) The entrepreneurship movement has its critics, especially among those who see college as a time for extensive academic exploration. "I just don't think that entrepreneurship ranks so high in terms of national need," says Daniel S. Greenberg, author of Science for Sale: the perils, Rewards and Delusions of Campus Capitalism. Leonard A. Schlesinger, Babson College's president, says that the question of whether innovation can really be taught is "an age-old argument".

单选题Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be founding standarddictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society ; second, a diverse population with a large number of subgroups ; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard," "colloquial," and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language wilt be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.
